Someone postpones consumption, invests his savings to produce a good or service, delights customers, generates profits, and then consumes and invests what’s left in further production. These profits are pure, generated from price signals between buyers and sellers, without favoritism from experts or elites. It isn’t hard to grasp.

Profit is the ultimate measure of value to consumers—and therefore to society. Consumers benefit from buying stuff, or else they would make it all themselves, and producers benefit from selling, or else business wouldn’t be worth the effort. Of similar value, profits go both ways.
